Great chargers for cheap. I use these on my lithium 150ah batteries. They run my diesel heater and my led lights, cell charging. My backup for when the power is out for days on end 😀

It's a lipo4 capable charger, but it barely float charges, if it does at all. It cuts as soon as the battery bms says charged. You won't be able to top balance w this if that's what you're thinking. But it'll charge to 100%. Kinda salty I got it for $68 on BF. Oh well. Seems like all of Ecoworthy stuff is falling. I hope everything is ok w them.

Not the fanciest but does the job, fan a little loud. I use mine to charge 12V 100Ah or a pair of them (series connection).

Bought the battery that was on sale and needed a review before committing to a mppt charger. Thanks for your post. Would'be been annoyed at what you experienced. Aliexpress has a (basically) no return policy - most items are decent from aliexpress but sometimes you get some half assed junk (but technically fits product listing description)

This is interesting information. So what type of charger actually does better at keeping those LiPo4 battery healthy?

Will this work to top off some li-ion cells? I put together a few 12v cells using 18650s.

Float charging is not healthy for lithium batteries. Charge them to 100% and use them. Keeping them at 100% will reduce their lifespan. if storing them, I'd keep them at 50-80%

Correction***:

It's a lipo4 capable charger, but it barely ***ABSORPTION*** (not float) charges, if it does at all. It cuts as soon as the battery bms says charged. You won't be able to top balance w this if that's what you're thinking. But it'll charge to 100%. Kinda salty I got it for $68 on BF. Oh well. Seems like all of Ecoworthy stuff is falling. I hope everything is ok w them.
